To alZ whont it ntagl concern/.-

Be it known that l, HERBERT it. lr'OUNc, a citizen of the United States, residing at Lakeport, in the county of Belknap and State oi New Hampshire, have invented certain new and useful Improvements in .i'ieviees lor House-firing; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it agpertains to make and use the same.

This invention relates to certain new and useful improvements in devices for housewiring; and it has for its objects, primarily, to dispense with the hook on the iishingevire heretofore employed for running 'lres out of sight. It is adapted to be applied to the end of the fishingqvire in any suitable manner and is adapted for use in connection with a piece of chain known in electric wiring as the jack-chain. The bodyot' the device is made of steel and is magnetized and is provided at the end with a plurality of hooks pointing in diiferent directions. When the body of the instrument comes in contact with the chain, it immediately attracts it, and when it is pulled along the chain slides down the tapered end and engages one of the hooks. The body of the instrument is made the same diameter as the hooks, so they will not eaten on any obstruction that may be in the path.

Other objects and advantages of the invertion will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.

lhe invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a par of this specification, and in which Figure 1 is a detail in vertical section showing the application of the invention. 2 is a side elevation of my improved instrument. Fig. 3 is a vertical section through the same. Fig. a is an end view.

Referring now to the details of the drawing's by letter, A designates the body of the device, which is made of steel and is magnet ized. One end is tapered, as shown at a, and at said end are a plurality of hooks extending' in diii'erent directions therefrom, the body of the instrument being of the same or greater diameter than the hooks, so that the .av be in their patl will be understood that the invention is be employed for drawing the wires or other material through the conduit or other place where the device is employed.

in practice the device is designed to be attached to the end of the fishing-wire in any suitable manner, in thisinstance being shown as having a screw-'lu'eaded socket A, with which the wircot' a threaded portion thereon may be engaged.

Fig. 1 represents a section through the walls ant. flooring of a building and the manner of running; the wires through the same by the aid of the instrument forming the subjectmattcr of this application. Suppose it to be desired run a wire down i side a partition, as from a. to b. The iirst thing to be done would be to bore a small hole through the partition at a, drop the chain, with the string attached, through the same, and by listening at bwhen the chain is dropped it can be very nearly located. Then the second hole is bored at Z), and the instrument, attached to a wire, is inserted through this hole and is moved about until it engages and catches the chain, when it is pulled out with the chain, it being understood that a wire is fastened to the string at the upper end, as at the point a, and by means thereof is pulled down through the space in the partition and out at b.

in Fig. E reprcsen ts the chain, and A the device forming the subject-matter of this application. The magnet attracts the chain, and the hooks secure it, as set forth. in a similar manner wires maybe run through under floors, as indicated at the top and bottom of the sketch.

As the device comes in contact with he chain, beings magnetized, the chain is imme diately attracted thereto, and as it is pulled along the chain slides down the tapered end and engages in one of the hooks.

'i plicity and advantages of the devices i rein described will be readily appreciatee. by those having occasion to use such v class or ceyiccs mpossible for the instrument rain without catching it on one heel-1s.

details may be resorted to or the Modifications in having a tapered end and a plurality of hooks at said end, substantially as described.

&. Lin electricians implement for running Wires, comprising a magnetized body portion haring a tapered end and a plurality of hooks at said end, and a screw-threaded socket at the other end, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

HERBERT. R. YOUNG.
